…then Christ doesn’t want any chemicals used on it to get rid of the weeds. He doesn’t want any well-meaning gardeners to attempt to cleanse the field from its chaff. He knows who is responsible for the weeds. “An enemy has done this.” The devil has sown his own seed in this same field. He has planted his seeds of doubt and false belief in the hearts of men. But our Lord is more concerned about the damage that will be done to the faithful if the wicked are uprooted before the time of the harvest.
